An all-carbon counter electrode for highly efficient hole-conductor-free organo-metal perovskite solar cells
Abstract
An all-carbon counter electrode has been fabricated for hole-conductor-free organo-metal perovskite heterojunction thin-film solar cells by a simple and low-temperature process. The counter electrode consisted of two parts: a mesoscopic carbon layer for good contact with the perovskite layer, and a piece of industrial flexible graphite sheet as the conducting electrode. Several types of carbon materials were employed in the counter electrodes and tested. From an electrochemical impedance study, it is found that the contact between the counter electrode and perovskite layer has a significant influence on the charge transport properties of the cells. A power conversion efficiency up to 10.2% has been achieved by hole-conductor-free mesoscopic CH3NH3PbI3/TiO2 heterojunction solar cells with the counter electrode containing a composition of graphite and carbon black, which inspires a new promising route towards low-cost and large-scale commercialization of perovskite solar cells.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
